Yes that's correct - Bombay Sapphire Distillery at Laverstoke, housed in the old Portal's Paper Mill (Listed) buildings (Portals, for hundreds of years, used to manufacture the paper for banknotes).
The Glasshouses show off the botanicals they use to flavour the Gin.
The Stills produce 80,000 lts/day using vapour infusion but is then transported back to the original site for bottling in Warrington.
Comes out at 80% but is then diluted with water to 40 to 47%. They let you taste the strong stuff by dipping a finger into it - full of flavour and pretty yummy!
The flavours change throughout the daily process - they sell the initial and last batches for alcohol production but blend the rest of the output to reach their required flavour/taste.
At the end of the tour they make you a cocktail, to your tastes, using a double Gin measure
or if driving a take away bag.
A nice few hours and well worth a visit.
